Question
Why does DivX 5.1 encode slower?
Answer
There's a simple explanation for this
Slowest mode in 5.05 = Standard mode in 5.1 (roughly).
In 5.1, Slow/Slowest modes implement a new algorithm, known as the rate distortion algorithm. Essentially, the RD algorithm squeezes higher quality still out of any given bitrate by carefully choosing frame and block types in order to save bits while encoding.
The quality improvements can be quite significant.
A performance tip:
Do all but your last pass in Standard mode with the MV file enabled. Then, disable the MV file (this is imporant) and switch to Slow or Slowest mode for your final pass. If you use Psycho-vis then you can also disable it until your second-last pass as long as you disable the MV file at this point (e.g. if you're doing 4 passes, turn on PV and turn off MV in pass 3).
My request is to know if a new patch to GordianKnot is possible to make some changes like text above.
Did GordianKnot make any changes in a speed mode avs file?
Thanks.
